The results of a routine water sample from the Skyview/Mooney Mountain water system in Roxbury contained a higher lead concentration than the level recommended by the U.S. Environmental Protection Agency, according to the township water department.

Public notices will be sent to the 688 homes in the affected water system, as required by the state -- the rest of Roxbury was not affected, according to a statement issued today by the township. That's because the lead comes from the old plumbing fixtures of houses in that area, not underground wells, it said.

The township said residents do not need to take special precaution or boil their water before use, and it's safe to drink or use for cooking and bathing. But those concerned about their water quality can run cold water for about 15 to 30 seconds before using it.

Roxbury conducts yearly routine water tests, and this announcement is the result of a water sampling taken on July 24. The township said it will now sample the water every six months instead of annually, as an additional precaution.

Residents interested in having their water tested should contact the town's health department at (973) 448-2028. There is a $45 fee per test.
